IPC: B23K15/00
Filed: 1982-02-22
Abstract: PURPOSE:To obtain a weld zone of stable quality by simple operation, by forming stepped joining faces on a turbine blade and an erosion shielding piece and  electron beam welding a filler wire to a groove aperture formed by the joining  faces in two steps. CONSTITUTION:Stepped faces 6a, 6b and a contact face 6c are formed on a turbine blade 6, and stepped faces 7a, 7b and a contact face 7c are formed on an erosion shielding piece 7. The contact faces 6c, 7c are brought into close contact and groove apertires 8a, 8b are formed by stepped faces 6a, 7a and stepped faces 6b, 7b. The first filler wires 9a, 9b are inserted into the bottom of apertures 8a, 8b and fixed, and the first layer weld zone 11 is formed by irradiating an electron beam. Then, an electron beam 14 is irradiated again while feeding the second filler wire 13 from a reel 12 onto the first layer weld zone to form a main weld zone 15. By this way, danger of generating weld cracks can be reduced.

Title: Antiskid control device
Inventor: HIGASHIMATA AKIRA
IPC: B60T8/58
Filed: 1989-02-08
Abstract: PURPOSE:To perform antiskid as aimed by a method wherein a rule according to which a solenoid valve drive time at which a wheel cylinder liquid pressure is caused to coincide with a target value is determined is set, and based on the rule, the solenoid valve drive time is decided. CONSTITUTION:A difference between a master cylinder liquid pressure by an initial pressure detecting means and a wheel cylinder liquid pressure by a brake pressure detecting means is computed by a differential pressure computing means. A pressure error computing means determines an error by which a wheel cylinder liquid pressure is deviated from a target value. A relation set means selects test data to determine a solenoid drive time responding to the error by means of a set means, and the result is specified at a solenoid valve drive means. Thus, even when a solenoid valve is differed in not only a drive time but also a pressure change amount with the direction of the error, a master cylinder liquid pressure, and a pressure difference, a solenoid valve drive time can be determined so that an error is reliably reduced to zero. This constitution enables performance of antiskid control as aimed.

Title: Piezoelectric coupler
Inventor: IKEDA TERUYUKI
IPC: H03H9/00
Filed: 1990-02-06
Abstract: PURPOSE:To form a small-sized coupler by a method wherein a first piezoelectric element and a second piezoelectric element which are provided with respective counter electrodes are connected mechanically via an insulating layer and they are fixed to a support frame. CONSTITUTION:Since two piezoelectric elements 12, 14 are fixed to a support frame 17, the first piezoelectric element 12 is extended when an electric field is applied to a drive terminal 18. Then, the extended portion is exerted on the second piezoelectric element 14 as a pressure, and a voltage is generated. Consequently, an output voltage corresponding to a change in the driven voltage is generated at an output terminal 19. As a result, when a voltage which is changed in a pulse shape is applied to the drive terminal 18, a coupler whose output is changed according to the change is formed. On the other hand, when an AC voltage is used as the voltage applied to the drive terminal, its output voltage is changed by a frequency.

An arithmetic circuit 5 exerts the arithmetic of A<2>-B2 upon the inputted signal and the differential value corresponding to the amplitude difference between the constant amplitude waves A and B is applied through a low-pass filter 6 to the voltage controlled oscillator 2 as a control signal for correcting the phase error. The constant amplitude waves A and B are separately inputted to amplifiers 3 and 4. The amplifiers 3 and 4 are equipped with an amplifica tion factor (k) and since the input signals are the constant amplitude waves fixing the amplitudes of envelopes, non-linear amplifiers with high efficiency such as a C-level amplifier, etc., can be used.

Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a pachinko machine capable of detecting the case when a ball entered within a big prize-winning port blocks the port and is not discharged normally from the big prize-winning port. SOLUTION: When the number of prize-winning ball detected by prize-winning detectors 25a, 25b and the number of discharged balls detected by residual ball detectors 33a, 33b are compared with each other. When the number of the prize-winning balls and the number of the discharged balls are not coincident with each other at the point of the time when a prescribed period passes after a variable prize-winning ball device 20 comes into a first state (open state), this is judged to be abnormal. Thus, since the noncoincidence of the number of the prize-winning balls and the number of the discharged balls is detected as abnormality in the case of this though the prescribed period passes after the device 20 comes into the first state, clogging of the inside of the device 20 is detected as abnormality.

In this state, the ring coupling member 20 can be rotationally moved, however, the movement in the light axial direction is restricted.  This constitution can eliminate any necessity of forming a holding groove so that a focus adjustment mechanism in assembling can be miniaturized.
